This fixes a kernel oops when unloading the driver due to usb_put_phy being called after usb_phy_generic_unregister when the device is detached. Calling usb_phy_generic_unregister causes x->dev->driver to be NULL in usb_put_phy and results in a NULL pointer dereference.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
